Pre-Painted Galvanized Iron
- Base Metal: Cold Rolled Steel (CR)
- Metallic Coating:Zinc (Zn) – 100% zinc coating
Corrosion Resistance: Good, but not as durable as PPGL in marine or industrial environments
Typical Lifespan: Shorter in coastal/humid areas
Common Uses: Roofing, wall cladding, appliances, automotive parts
Pre Painted Galvalume
Base Metal: Cold Rolled Steel (CR)
Metallic Coating: 55% Aluminium, 43.5% Zinc, 1.5% Silicon (Al-Zn alloy)
Corrosion Resistance: Superior – better performance in harsh, coastal, or acidic environments
Typical Lifespan: Longer than PPGI due to the aluminum in the coating
Common Uses: Roofing (especially near the sea), construction, solar panel mounting structures
